Respect Authority.

I am beginning to think that we need public service announcements on TV to remind people how to act when a police officer is speaking to you. It doesn't matter if you think you have been unfairly stopped. It doesn't matter if you don't trust cops. When a cop tells you to get out the car or turn around or put your hands on your head, YOU DO IT! Discussions can happen later.

Because you if you don't, things like this can happen.
